Step-by-step Instructions to Setup an AWS ECS Cluster

Configuring AWS ECS to have access to AWS EFS

If you would like to persist data from your ECS containers, i.e. hosting databases like MySQL or MongoDB with Docker, you need to ensure that you can mount the data directory of the database in the container to volume that's not going to dissappear when your container or worse yet, the EC2 instance that hosts your containers, is restarted or scaled up or down for any reason.

Don't know how to create your own AWS ECS Cluster? Go here!

New Cluster

Sadly the EC2 provisioning process doesn't allow you to configure EFS during the initial config. After your create your cluster, follow the guide below.

New Task Definition for Web App

If you're using an Alpine-based Node server like duluca/minimal-node-web-server follow this guide:

Compojure-api and Buddy
  • (:identity req) is auth backend independent way to access user data
  • login and logout implementation depends on auth backend
  • :current-user doesn't imply that authentication is required, route should also have :auth-rules if authentication is required

Translate prismatic's schema.core errors to a human readable form. Use this for presenting validation errors to users. Don't use this for programming errors like a missing map key etc.
(ns x.y
(:use [plumbing.core]) ;; Just for the map-vals
(:require [clojure.walk :refer [postwalk prewalk prewalk-demo postwalk-demo]]
[clojure.core.match :refer [match]]
[schema.utils :refer [named-error-explain validation-error-explain]]
[schema.core :as s])
(:import (schema.utils NamedError ValidationError)))
